BOTANICAL: Agapanthus orientalis (syn: A. praecox var. orientalis)

BLOOM

LIGHT
Late spring to early fall
1 ft. - 5 ft.
Full sun to part sun

TYPE: Tuber

COLORS: Blue or white

STORAGE AND SPECIAL TIPS: Plant 1-inch deep in the spring. Allow container bulbs to become root bound, and only divide every 5 years. Additionally, if planting inground, these beautiful plants tolerate winter frost well, and they can recover fully even if they freeze. To help them along in winter, apply mulch around their base and plant them closely together. Planting near the foundation of the house also helps provide protection from frost. If planting in extremely cold winter areas, store over winter in their pots, under cool storage conditions.
A. orientalis 'Tinkerbell', 18", is an unusual variegated variety.

COMMENTS: Plant 8-inches deep, 10-inches apart.This is one of the loveliest ornamental onions and a native of Turkey. The 2-1/2 inch bulb produce 3-inch, round-headed flower heads with hundreds of tiny florets opening into star shapes above 6 to 8 gray-green leaves. Make initial plantings 8-inches apart in early fall in an average, well-drained, sandy soil. All allium demand a well-drained site. Once allium start blooming, the leaves begin to yellow. Planting them among lower plants hides the fading foliage, or remove unsightly foliage..

COMMENTS: Plant 4-inches deep and 3-inches aprt. A native to the Iberian peninsula and extremely hardy and very showy when in full bloom. The flowerheads, 2- to 3-inches across, stand out erect from 1-inch wide, light green, fleshy leaves. Will succeed in average soil providing it is well-draining. Plant the bulbs 3-inches part and 4-inches deep. The leaves tend to flop untidily after blooming but I cut mine off as soon as they begin to yellow without causing harm, evidenced by an increasing patch size. A. Moly is inexpensive and multiplies well.
A. moly 'Jeannine' produces two flower stalks instead of one.

COMMENTS: Reasonably simple to grow, the tuberlike rhizomes require a full season after initial planting to establish the large root system it needs for blooming. Basal clumps of narrow, reedlike foliage up to 1ft. long surround the single flower stalk with its 10 to 20 star-shaped, 1-inch, fragrant florets. It needs a rich moist, sandy, humusy soil with abundant water when in bloom.

6" - 1 ft. x equal spread
Light to full shade

TYPE: Rhizome

COLORS: Grown for their colorful textured leaves.

STORAGE AND SPECIAL TIPS: Use 3 or 4 tubers per grouping, 8- to 10-inches apart, planted stem side up, tops slightly above soil in the ground or in pots and hanging planters. The ornamental heart-shaped leaves can be up to 1 foot long, with striking patterns in variations of red, black, silver and green with a rippled or pimpled surface. They grow in a mounding habit to approximately 1 foot in height and vary in width to 18-inches. The small flowers are inconspicuous. B. rex appear to be a favorite among hybrizers who manage create the most extraordinary leaf patterns. Place them in pots in the shade garden during the summer, and bring them indoors for the winter. Fertilize lightly but regularly, and do not allow them to dry out. The soil must be highly fertile and very well draining. Lift, dry and store over winter under cool conditions. Hardy in Zones 10 - 12. Proven Winners introduced two interesting cultivars in 2003:
B. rex
'Boston Cherries & Chocolate'.
B. rex

COMMENTS: Plant 3- to 4-inches deep after soil has warmed. Accepts average soil. Plant 2 ft to 4 ft. apart. Canna have been hybridized of the years, and now are there is an amazing array of cultivars of varying sizes and colors available. Look for the varieties with variegated leaves. They are very attractive. Canna leaves tend not to be attractive, so plant something smaller in front of them. Not all canna are hardy so check the plant tag. Lift non-hardy rhizomes, dry and store under warm storage conditions. Although I garden in Zone 6, I have successfully overwintered canna without any special attention. Many are hardy to zero degrees F.

ZONE

Sun

TYPE: Corm

COLORS: Pink or white

COMMENTS: Plant 3- to 4-inches deep in the fall in a sandy, organic soil. The planting of these large corms should occur as soon as they appear in the local garden nursery or arrive by mail, as they flower very early even out of the earth. Capable of producing its elongated blossoms just sitting openly on a windowsill (because the bud was long pre-formed), this plant should be planted in moist, well-drained, average soil. Do not remove any foliage before it fades or the corm will diminish in vigor or possibly fail to bloom. Shown, C. a. pleniflorum, is a double-flowering variety. Crocus can be distinguished from the Colchicum by the number of stamens; the Crocus has three, while the Colchicum has six.

COMMENTS: Plant pips 1- to 3-inches deep, 4- to 6-inches apart, in the fall. Slow to develop, but once established requires little maintenance. This sweetly fragranced plant has been a favorite since the 16th Century. It thrives in rich, moist, humusy soil. An annual topdressing of compost is useful. When overcrowded, the blooms diminish, therefore, division is needed. The very fragrant flowers turn to brilliant red berries. Hardy to minus 40 deg. F, this hardy plant forms dense seasonal mats. Mulch over winter until established.

TYPE: Corm

COLORS: Brilliant red, yellow or orange.

COMMENTS: Plant corms 3- to 5-inches deep in spring. Crocosmias are members of the iris family and have swollen underground corms that increase freely to form sheaves of sword-shaped leaves. Unsurpassed for blazing color and elegance, the robust plant displays intensely colored and unusual blossoms which hang on the end of arched, wiry stems. Best planted in large displays but may need to be lifted in Zone 5, or very heavily protected over winter, although the picture is of a plant I have successfully grown inground for many years. Provide a well-drained, moist, humusy soil. Highly attractive to hummingbirds.
Crocosmia
'Canary Bird' is a golden yellow, as is 'Jenny', and 'Norwich canary' is a bright yellow.

Full sun
3 - 9

TYPE: Corm

COLORS: White, purple, lavender, orange, yellow or gold.

COMMENTS: Plant 5-inches deep in the fall. Excellent in pots, in the lawn and the mixed border. Very easy to grow requiring little or no attention. One of the first spring flowers to bloom. Congested clumps may need to be dug and divided. This should be performed after the leaves have withered. There are numerous cultivars available:
C. chrysanthus. Many chalice-shaped, stemless flowers emerge from each tiny bulb before the 4 to 6 white-lined, grassy leaves develop. Colonize readily in dense masses.
Crocus speciosus is one of the easiest autumn crocus to grow. It has attractive, striped, funnel-shaped, 2 -1/2 inch fragrant blossoms. The stigma becomes deep orange-red. Most flowers appear either before or with the emerging leaves.
C. tommasinianus, another late winter bloomer, bears long, tubed flowers, varying in color from lilac or purple to violet, sometimes with darker tips to the petals, and occasionally silver outside. Naturalize well.
C. vernus, a Dutch crocus is a late winter bloomer and varies in color from white to purple or violet, often striped or feathered. Stigmas are large, frilly and orange or yellow.
