'FAQ:2004:3 - Lily Bulb'

Asiatic hybrids are generally best suited to areas of bright light, but can also take some light shade throughout the day, without "stretching" too much. Trumpets and Orientals like to have 4 hours or more of sunlight to be at their best. This could be spots of sun scattered throughout the day, or a couple hours in the morning followed by a couple of hours in the afternoon, as long as it added up to 4 hours or more of bright light on their leaves.

In areas of high heat, Orientals prefer to be in light to moderate shade throughout the hot afternoon hours or in dappled shade all day long. Trumpet lilies will tend to grow very tall and will need staking if given too much shade, if you are unsure as to whether or not to stake, try placing a short, 12" wooden stake next to the bulb when you plant, then if more support is needed, simply replace the "marker" stake with a taller one. Try the new upright (Angel Series) for stronger stems with less need for additional support.

Species lilies have varying requirements, special instructions for success is in the description. In general, L. regale can be grown as any Trumpet; L. speciosum var. Uchida treat as an Oriental Hybrid; L. superbum needs protection from the wind and a partly sunny, moist area and Martagon Hybrids prefer well-drained soil in light shade.
