Endless Allium Bulb Collection
DetailsThe Endless Allium Collection is a deer/rabbit resistant combination for gardeners who want to see Allium blooming as long as possible in their garden. The “fireworks” start with the deep magenta-pink blooms of Allium ostrowskianum in early spring. These bulbs will add a lovely contrast to Allium Violet Beauty, which will bloom at nearly the same time. These two will be followed by Allium Purple Sensation (a long-time customer-favorite) which will overlap bloom time with the true-blue blooms of Allium azureum in early summer. Allium can add interest to your garden all season long, so no need to trim back the spent Allium blooms. (A few of our customers have gotten creative and spray painted the dried blooms for season-long color—this will make your garden visitors double-take for sure!) Collection of 88 bulbs; Cold hardy in zones 4-8. Deer/rabbit resistant.

Tips on Growing Fall Planted Flower Bulbs
When you receive your spring bulbs (tulips, daffodils, etc.) keep them in a dry, dark, cool place until ready to plant. They need air circulation so they will not collect moisture and rot. Planting times can vary from early October in the North to mid-to-late November in the southern regions. A good rule of thumb is to plant them about 6 weeks before the ground is frozen or after the first hard freeze. For more information and a planting depth illustration, see pages 14-16 of our Planting Guide.
Soil Preparation for Bulbs
A compost-enriched, well-drained soil is best. Incorporate a good quality organic compost as needed. Yum Yum Mix® is recommended as an excellent source of nitrogen, phosphorus, and potassium needed for strong plants and healthy roots. Mix a small amount into the bottom of the hole before planting your bulbs.
Many bulbs prefer full sun exposure. However, Muscaria, Allium, Galanthus, Hyacinthoides, Scilla and many Daffodils will tolerate partial shade and bloom well. Pink daffodils will hold their color longer if planted in dappled shade or morning sun/afternoon shade.
After planting, add a top dressing of compost or other organic material and water in thoroughly. If your winter is dry, water every three to four weeks throughout the winter and add more mulch if necessary.
Protect your Bulbs
Apply a mole or gopher repellent to the surface of the ground to protect bulbs from these burrowing mammals. As bulbs sprout, use our Deer Off Repellent to prevent deer and rabbits from browsing your spring blooms.
After your Bulbs have Bloomed
Once your bulbs have bloomed, allow the bulb foliage to brown and fade naturally since the leaves are feeding the bulb in the ground. Removal of foliage weakens the bulb and leads to fewer blooms the following year. Planting your bulbs amongst your perennials is one way to conceal the dying bulb foliage. The perennials begin to grow and fill out as the bulb foliage dies back. The perennials will then provide foliage and color in the garden from late spring through the summer and into fall. Regular fertilization with balanced organic or natural fertilizer and a re-application of mulch each fall will ensure more and more beautiful spring bulb blooms for many years!
Soil Preparation: Remember that proper soil preparation is the key to healthy, vigorous blooming perennials. Use Yum Yum Mix and a high quality compost at recommended rates to prepare the soil. Inoculate the plant roots with Plant Success mycorrhizal inoculant. Planting: Plant according to the mature size of the plant. Don’t be tempted to put the plants too close based on their size in the pots. They’ll grow quickly and cover the space shown in the planting map. (Maps included only with Pre-Planned Gardens, not Collections.)
Fertilizing: Once annually in mid-fall, after plants begin to go dormant. Use Yum Yum Mix or Yum Yum Mix Winterizer at recommended rates to improve the soil and provide essential plant nutrients.Use it with high quality compost, mix half and half by volume and spread on top of the soil. Scratch it in lightly and water thoroughly. It is also beneficial to treat the plant roots with Plant Success® mycorrhizal root inoculant if you didn’t do so at planting time. (Inoculation only needs to be done once.)
Mulching: In arid climates mulching is very beneficial. Coarse textured composts, shredded leaves, pine needles and composted bark are all excellent mulch materials. Apply to a depth of 1-2 inches. Replenish annually (or as needed).

Q & A

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
