For the plants I know, I try to include personal information - our likes and dislikes, what seems to work in our zone 6 garden, when it blooms and how tall it gets in our setting, etc. This information may not reflect habits and bloom times in other gardens (i.e., my website is not an encyclopedia).
For the plants I don't yet know so well, the information is most likely what I've been able to scrounge up from my own web searches. I try to go for the concensus opinion (it's amazing how many different colors, hardiness zones, etc. get attributed to the same plant!).
The seedstarting information is always mine, from personal experience. For more information, visit my seedstarting pages.
Feel free to print or otherwise use my pictures offline in any non-commercial way you want. If you want to use any photo on the web, or for any commercial purpose, please e-mail me for permission. In any event, please don't link directly to my photos - link to my portrait pages instead. And if you do use the photos in any kind of public way, please provide a reference (clickable link for web use, otherwise just text) to www.robsplants.com. Thanks!
Tip: If you're wondering about what time of year any of the pictures was taken - try looking at the name of the photo (in Internet Explorer, by right-clicking on it and choosing "properties"). In almost all cases, you'll find the date the picture was taken as part of the name, in YYMMDD format.
