Tulip, Siam


1. Light/Sun Exposure - Full to partial sun.

2. USDA Hardiness Zones - Garden hardy in-ground in zones 9-10.  In cooler zones (1-8) bulbs should be lifted in the fall and stored.

3. Planting Distance - 2 feet apart in ground.

4. Mature Height/Spread - 2 feet tall.

5. Bloom Time - Summer.

6. Planting Instructions - Dig a hole twice as deep and twice as wide as each dormant rhizome. When dug, the hole should be big enough to allow the rhizome to be covered with 2 to 3 inches of soil.  Place rhizome in hole and cover with soil, firming the soil with your fingers. Water thoroughly.


Siam Tulip produces gorgeous dark, rose pink inflorescence (flowers) which are held high above the foliage for maximum effect. Our white selection has the same growth pattern but is alabaster white in color. They present a charming 'duo' when in bloom. The flowers are extremely long lived, either on the plant or as cut flowers. They sport gorgeous narrow stiff leaves, which, ironically, also resemble the leaves of a tulip.


Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1.  Spade or till the soil to a depth of 12-18 inches.

2.  To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2 to 4-inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3.  After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.


Water - Your plants require 1" of rainfall (or equivalent watering) each week when planted in the ground.  Do not allow plants in containers to dry out.  In a container that is exposed to full sun, water it well at least once every other day, and possibly every day, during periods of intense summer heat.  You may wish to temporarily move containerized plants to an area where they are shielded from the hot summer sun (i.e., in the shade of a tree, on a porch near an overhang).

Mulching - Apply a 2-4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them.

Grooming - Clip off dead or unsightly growth to maintain attractive form and shape.  Deadhead or remove flowers when blooms have faded, leaving as much foliage as possible.  As long as the foliage remains green it will gather sunlight and transmit energy into the root system for the following growing season.    

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster.  Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing - In ground plantings will go dormant in the ground in zones 9 through 10.  In zones 1 through 8, you will need to lift (dig) the rhizomes in the fall after the first light frost.  Remove all the old foliage, pack in dry peat moss or wood shavings, and store the rhizomes in a location where the temperature stays around 50 degrees F.

Containerized plantings can be moved indoors to a cool spot (i.e., unheated garage, shed) in winter where the plants will go dormant in the container.  Water them lightly very 7-10 days. 

In the spring after danger of frost has passed, move potted containers back outside and/or replant the rhizomes outdoors in pots or in the ground.


CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested.
