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).

Our The Sky’s The Limit Bulb Collection will make it easy to add bold color to the landscape. Varying shades of blue and purple tulips and alliums are highlighted by cheery yellow daffodils. Starting in spring, Grape Hyacinth makes lovely edges and will easily naturalize to form rivers of blue color. Our Blue Moon Triumph Tulip Mix creates a harmony of purple, rose, pink, and plum shades. Mix with Dutch Master Trumpet Daffodil, another mid-spring bloomer with pure yellow flowers that shine like the sun; deer-resistant daffodils naturalize well and will multiply year after year. Beginning in early summer, the Purple Sensation Allium are closely followed by True Blue Allium. Purple Sensation's fantastic, densely flowered purple globes are pure magic in the garden, and True Blue Allium adds a harmonious sky blue color to the mix. Alliums are highly critter resistant and some of our pollinator's favorite flowers. All bulbs in this collection will thrive in well-drained, compost-enriched soil in a mostly sunny location. We highly recommend using a trench-planting method for the easiest way to plant this quantity of bulbs! Great for new homes or when the older garden needs a pick-me-up, this is the perfect way to make a big impact.

The Sky’s The Limit Bulb Collection includes:

True Blue Allium - 80 bulbs

Purple Sensation Allium - 50 bulbs

Dutch Master Trumpet Daffodil - 32 bulbs

Grape Hyacinth - 64 bulbs

Blue Moon Triumph Tulip Mix - 50 bulbs

Planting Guides

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 13-15 of our Planting Guide.

Soil Preparation for Bulbs: Plant tulips in well-drained soil to ensure proper root formation. 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, including Tulips. Exposure to full sun will bring out the rich colors that tulips offer, but some shade will enable a longer blooming period and still offer a colorful addition to your yard or garden. Other bulbs such as Grape Hyacinth (Muscari), Allium, Snowdrops (Galanthus), Hyacinth, Scilla and many Daffodils will tolerate partial shade and bloom well, so long as they receive at least six hours of sunlight each day. 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: One planting of Yellow Crown Imperial per 20 feet of garden bed will deter foraging mice, voles and moles. To deter chipmunks and squirrels from snacking on Tulip bulbs, place a grid of chicken wire above the bulbs as you plant to protect them. Apply Chase Mole and 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 insure more and more beautiful spring bulb blooms for many years!
