I'll vote for late spring too.

But late summer/earliest fall comes next - even though I don't like those earthy and yellow tones that much either. Lochinch butterfly bush in lavender, purple asters, cone flowers, Sungold buddleia in soft yellow - twenty tiger swallowtails fluttering. Monarchs. Gangly tithonias proving that orange can be elegant.

Sedums absolutely alive with bees - bumble, honey and little emerald ones. Salvias and the roses making another flush of bloom - deeper colors on the roses, not all paled by the sun. No more Japanese beetles!

The vegetable garden at it's most abundant - melons, green beans, tomatoes at every meal, tomato sandwiches for a snack.

The tropical garden absolutely jungly. Hummingbirds coming through.

Deep blue clean fall sky. Summer haze blown south.

Yeah that is a plus to the late summer garden..... tons of veggies.... buckets of tomatos...... :) But oooh I hate sedums!!!! :) I've tried to like them because people recommend them but I just don't! My autum joy (for example) looks like broccolie to me. :) Buddleia is at least something delightfully "smelly" for the fall. :) Smells just like honey too me. But 2 votes for late spring. :)
