Cheap and Easy to Tend seasonal plants for my garden tubs

You really can't beat Pelargoniums for being neglected.
The range of hybrids has increased.
I get mine in the local market .
If you are careful-you can winter them in your kitchen then as they will become leggy give them a cut and plant out after the frosts

Most other plants are too tender .
I always put my cooled used tea bags on top of the soil to keep moisture in .
I've got a huge variety of plants in my pots and all of them need watering almost daily .

I've had beautiful displays of iris germanica but you're left with just leaves for the rest of the year .
I recommend the variegated one.
Irises aren't thirsty plants .
Lavender is easy .After a few years it tends to become woody and ugly.
Rosemary is another idea .

Last year I had Tidal Wave Petunias, Osteospermum, Busy Lizzies and Fuschias in groups of pots. If you like profusion I would recommend them. They flowered right up to the first frosts.

Begonias, petunia, geraniums, impatient, nasturtiums

I'm going for begonias for shady spots and geraniums (sented leaf ones) for sunny pots. I always pot up a few nice grasses to mingle with them. I find one variety of anything often (to me) looks more spectacular than a mix!
