Ipheion is a group of bulbs that produce many star-shaped spring flowers in blue, white or purple. After flowering it dies back for the summer. Prefers a sheltered location, with dappled light and well drained soil, best planted in the fall. Good container plant in a cold greenhouse. I. uniflorum, syn. Tristagma uniflorum is a clump-forming perennial that produces single frangrant flowers 1 1/2 inches across with darke

FertilizingHow-to : Fertilization for Annuals and Perennials
Annuals and perennials may be fertilized using: 1.water-soluble, quick release fertilizers; 2. temperature controlled slow-release fertilizers; or 3. organic fertilizers such as fish emulsion. Water soluble fertilizers are generally used every two weeks during the growing season or per label instructions. Controlled, slow-release fertilizers are worked into the soil ususally only once during the growing season or per label directions. For organic fertilizers such as fish emulsion, follow label directions as they may vary per product.
LightConditions : Dappled Light
Dappled Light refers to a dappled pattern of light created on the ground, as cast by light passing through high tree branches. This is the middle ground, not considered shady, but not sunny either. Dappled remains constant throughout the day.
WateringConditions : Moist and Well Drained
Moist and well drained means exactly what it sounds like. Soil is moist without being soggy because the texture of the soil allows excess moisture to drain away. Most plants like about 1 inch of water per week. Amending your soil with compost will help improve texture and water holding or draining capacity. A 3 inch layer of mulch will help to maintain soil moisture and studies have shown that mulched plants grow faster than non-mulched plants.
PlantingHow-to : Planting Bulbs
Plant bulbs at a depth that is three times their height, and at least 1-1/2 bulb-widths apart. Work a little bone meal fertilizer into the bottom of your hole, and then place the bulb upright in the hole. The more pointed end is almost always the top. If you have trouble telling which is the top, look for evidence of where a stem or roots were last year. If in doubt, plant them sideways. Fill in with soil gently, making sure there are no rocks or clods that would impede the bulb's stem. When planting a great number of bulbs, dig out an area to the specified depth, place bulbs and replace soil. This ensures that ground has been properly prepared and bulbs are evenly spaced.
Plant bulbs in natural drifts rather that formal rows: bulbs can fail or be eaten, leaving holes in a formal arrangement, or will shift with freezing and thawing. If you have trouble with gophers or squirrels eating your bulbs, try sprinkling red pepper in the holes, covering the bulbs with chicken-wire, surround bulbs with sharp shards of gravel or other substance, or planting rodent-repelling bulbs like Fritillaria nearby.
