About this app

BloomLab+ is a seasonal guide for ikebana and flower arranging. It shows which stems are in bloom and at the market where you live, how to condition them, and which vessel each one suits.

NOW
Your home screen shows the stems in season for your region this month. Stems at their peak are marked Shun, and the Japanese solar term for the current fortnight sits at the top. Switch between In bloom (gardens and the wild) and At the market (what florists sell).

STEM PAGES
Each stem has its English, botanical and Japanese names, two season bars for your region (in bloom and at the market), and how well it works in a kago (basket), a nageire (tall vase) and a moribana (shallow suiban), with a reason for each. Mizuage steps help the cut stem drink before you arrange it. You also get vase life, stem length, form, colors, whether it is toxic to pets, and photo credits.

CALENDAR AND SEARCH
See all twelve months at a glance with the number of stems in season. Search by English, botanical or Japanese name, then narrow by month, vessel, role, color or pet safety.

IKERU PLANNER
Choose a vessel and a month. BloomLab+ suggests in-season stems for line, mass and filler, and says why each one suits the vessel.

REGIONS
Southern California is the baseline, reviewed by Valeria, a teacher in the Sangetsu tradition. Other US regions, Northwest Europe, Japan and the Southern Hemisphere are included and marked approximate. You can choose your region, or let BloomLab+ work it out once from your approximate location. Only the region is kept.

LEARN
A short guide to the three vessels, mizuage and how the seasons work, plus a link to Valeria's ikebana classes. Help & guides in Settings has how-to videos.

PREMIUM
Free includes Now, the Calendar, Search, every stem page, the top Ikeru pick for each role and up to 10 favorites. Premium adds:
- Ikeru planner: every in-season stem for any vessel, with saved plans and market lists
- My vessels: your own vases and baskets with their height and opening, so plans fit them
- My garden: mark the stems you grow and see when they are in shun

Premium is $3.99 a month or $19.99 a year, and the yearly plan starts with a 7-day free trial. Prices may vary by country. Payment is charged to your Google Play account. The subscription renews automatically until you cancel it in Google Play > Payments & subscriptions. Restore purchases is on the Premium page.

PRIVATE BY DESIGN
No account and no sign-in. Favorites, your garden, vessels, plans and the journal stay on your device. BloomLab+ collects no data.
