The past few gardens have has a sad theme for the generator seed. This week it's the weekend of the solstice. If you live in the Northern Hemisphere you have the longest days, and lazy summer evenings. If you live in the better hemisphere, then you can look forward to the dark nights fleeing and spring returning.

For plants the solstice might well be a useful signal. The photoperiod, the period when plants are exposed to light starts to reduce. Combining this with other signals, like temperature could act as environmental cues for changes in processes that a plant invests in.

It's also suggested that it could be used as a signal to coordinate plant processes across a wide area, like mast seeding, periods when plants produce an abundance of seeds all together to overwhelm any granivores that might feast on them.

How to Play

Six plants fill each row
each column, each box of six
no bloom may repeat

Tap an empty cell
then choose your plant from below
watch the garden grow

Or pick a plant first
then tap the cells where it goes
faster hands plant more

Red borders will warn
when two alike share a line
rethink and replant

Ticked plants rest complete
all six placed in rightful soil
fewer choices left

The clock starts to run
the moment your first plant falls
how swift is your hand?

Every row, column & box needs all six plants
0:00

Select a plant, then tap cells

0/36 planted

Two ways to play: Tap an empty cell then pick a plant, or select a plant below then tap cells to place it.
